Clinical, histological and safety outcomes with long-term maintenance therapies for eosinophilic esophagitis: A systematic review and meta-analysis. Maintenance therapies prevent histological relapse in the long term, without clear disadvantage of dose de-escalation from induction to maintenance phase. Low adverse events and withdrawal rates confirm long-term treatment is well tolerated. |
Comparative Efficacy and Safety of Endoscopic Modalities for Colorectal Cancer Screening in Inflammatory Bowel Disease: A Systematic Review and Network Meta-Analysis. HD-DCE is the only modality for IBD surveillance with evidence (low-certainty) demonstrating potential to detect more dysplastic lesions compared to HD-WLE. There was no evidence to support any of the other modalities as an alternative due to very low-certainty evidence. |
Global epidemiology and characteristics of MASLD in type 1 diabetes mellitus: an updated systematic review and meta-analysis. MASLD is relatively common in T1DM. Patients with MASLD-T1DM have a distinct clinical profile compared to those with T1DM, with only a small proportion having significant or advanced fibrosis. |
Predictors of Post-ERCP Pancreatitis: A Comprehensive Systematic Review and Meta-Analysis. Our meta-analysis focused on adjusted risk factors to provide precise estimates of the most important risk factors for PEP.

Risk-Adapted Starting Ages of Colorectal Cancer Screening for People With Diabetes or Metabolic Syndrome. People with diabetes or metabolic syndrome reach risk levels comparable to the average risk population three to four years earlier. Our results offer empirical guidance for defining risk-adapted starting ages of CRC screening for these high-risk groups. |
Virological and Immunological Characteristics of HBeAg-Positive Chronic Hepatitis B Patients With Low HBsAg Levels. HBeAg-positive CHB patients with low HBsAg and genotype C exhibited higher noninvasive fibrosis indexes compared with typical patients, accompanied by a significant increase in quasispecies variants associated with preS2 deletion. The emergence of the preS2 deletion mutants in patients could be due to its enhanced ability to evade the host immunity. |

Efficacy and safety of transcutaneous auricular vagus nerve stimulation in patients with constipation-predominant irritable bowel syndrome: a single-center, single-blind, randomized controlled trial. The study manifested that non-invasive taVNS effectively improved constipation and abdominal pain symptoms in IBS-C patients. The alleviation of IBS-C symptoms may be attributed to the integrative effects of taVNS on rectal functions, mediated through vagal, cholinergic, and multi-omics mechanisms. |
Evaluating Artificial Intelligence-Driven Responses to Acute Liver Failure Queries: A Comparative Analysis Across Accuracy, Clarity, and Relevance. The study highlights Chat GPT 4 +RAG's superior performance compared to other LLMs. By integrating RAG with LLMs, the system combines generative language skills with accurate, up-to-date information. This improves response clarity, relevance, and accuracy, making them more effective in healthcare. However, AI models must continually evolve and align with medical practices for successful healthcare integration. |
Proximal polyps are associated with higher incidence of colorectal cancer: Analysis of the Minnesota Colon Cancer Control Study. Although patients with proximal adenomas were found to have higher hazards of post-colonoscopy CRC, adjusting for polyp multiplicity attenuated the strength of association. Further research is warranted to determine whether polyp location should be factored in the determination of appropriate surveillance intervals. |
The Role of Gastroesophageal Reflux in Airway Inflammation. Both experimental and clinical studies have shown that aspirated refluxate can directly damage the airway lining and trigger immune responses that contribute to airway injury and inflammation. While traditional diagnostic tests for gastroesophageal reflux disease can identify abnormal reflux patterns, there is a need for more specific methods to predict airway inflammation or therapeutic outcomes related to reflux aspiration. |

A randomized phase 2 study of efmarodocokin alfa, an IL-22 agonist, versus vedolizumab in patients with ulcerative colitis. Efmarodocokin alfa did not demonstrate efficacy compared to placebo and this phase 2 study was ended early for futility; however, there was evidence of target engagement (skin AEs, REG3A levels); NCT03558152. |
Acute Kidney Injury in Patients with Cirrhosis and Chronic Kidney Disease: Results from the HRS-HARMONY Consortium. In hospitalized patients with AKI and cirrhosis, AoCKD was associated with lower 90-day mortality compared to AKI-only. This may be due to the impact of worse liver function parameters in the AKI-only group on short-term outcomes. Further study of the complicated interplay between acute and chronic kidney disease in cirrhosis is needed. |
Efficacy and Safety of Budesonide Orodispersible Tablets for Eosinophilic Esophagitis up to 3 Years: an Open-Label Extension Study. Clinical and histological remission of EoE could be maintained with BOT in a large majority of patients for up to 96 weeks, and for up to 144 weeks in patients with uninterrupted BOT therapy across al trials. No additional safety concerns were identified with long-term BOT treatment. (ClinicalTrials.gov, Number NCT02493335). |
Endoscopic sleeve gastroplasty plus lifestyle intervention in patients with MASH: a multicentre, sham-controlled, randomized trial. Baseline to end of follow-up changes in body weight, liver tests, liver stiffness(VCTE) and liver histology were recorded RESULTS: Total Body weight loss(TBWL) was 9.47%(±9.38) in ESG group vs 3.91%(±5.43) in ESI group(p 10% we found a significant improvement on NAS score(-4±0.94 vs -0.81±1.62, p<0.01), but not in fibrosis stage(-0.3±1.06 vs -0.59±1.25). Only 2 patients of ESG group had adverse events that required admission that resolved conservatively in 72 hours CONCLUSION: ESG is an effective and safe method to promote weight reduction associated with significant improvement in patients with MASH and obesity. |
Global Trend of MASH-associated Liver Cancer A Systematic Analysis from the Global Burden of Disease 2021. Over the past two decades, the burden of MASH-associated PLC has risen, though there are sociodemographic and geographic disparities. This necessitates urgent strategies across the globe to mitigate the epidemic of MASH-associated PLC as well as its metabolic drivers. |
Hypercoagulation after Hospital Discharge in Acute Severe Ulcerative Colitis: A Prospective Study. Global measures of haemostasis demonstrated that patients with ASUC were pro-thrombotic compared to controls with quiescent colitis. This difference was maintained 8 to 12 weeks after the initial presentation, supporting clinical observations that patients with ASUC have an elevated risk of VTE after hospital discharge. |
Inadequate Efficacy of Biologics for Treating Proximal Ileal Lesions in Crohn's Disease; a prospective multicenter study. A substantial proportion of patients with CD exhibited ulcerations in the proximal ileum which correlated with a poorer prognosis. These lesions proved challenging to heal, regardless of the type of biologic used. |
Lipoprotein (a) in the Full Spectrum of MASLD; Evidence from Histologically and Genetically Characterized Cohorts. The inverse association observed in cross-sectional studies should be attributed to reverse causality i.e. the presence of liver disease may decrease Lp(a) levels. Genetically predicted very low Lp(a) levels are also associated with impaired liver health prospectively. Clinical trials evaluating Lp(a)-lowering agents should thus be monitored carefully for adverse liver effects in subjects attaining extremely low concentrations. |
Neighborhood social determinants of health are associated with metabolic dysfunction-associated steatotic liver disease outcomes. Neighborhood-level SDOH are associated with MASLD burden, comorbidities, and mortality and should be considered in clinical care, quality improvement, and further research. |
Non-alcohol-related cirrhosis leads to higher 6-week mortality after acute variceal bleeding than alcohol-related cirrhosis. Patients with non-ALD cirrhosis presenting with AVB had a higher risk of 6-week mortality, at each severity of liver disease by standard indices, than patients with ALD cirrhosis. Cirrhosis etiology (ALD versus non-ALD) should be incorporated into the risk stratification of AVB patients. |
Non-invasive assessment of portal hypertension in patients with primary biliary cholangitis is affected by severity of cholestasis. Biochemical-based RESIST criteria demonstrate the highest net benefit compared to elastography-based criteria for ruling out HRV. The severity of cholestasis affects NITs performance to rule out HRV and CSPH in patients with PBC and cACLD. |
Prevalence and Prognosis of Mild Inflammatory Bowel Disease: A Population-Based Cohort Study 1997-2020. Approximately one-fourth of individuals with mild UC within one year after diagnosis and half of those with mild CD progressed to moderate-severe disease over time. Young age at diagnosis increased the probability of progression, whereas increasing duration of mild disease decreased the probability. |
Serum Albumin and Its Trajectory Are Associated with Therapeutic Outcomes in Ulcerative Colitis. Higher albumin levels were associated with better therapeutic outcomes in patients with UC. However, patients with low but rapidly ascending albumin levels would achieve outcomes comparable to those with medium-to-high levels of albumin. |
THE OPTIMAL DURATION OF pH-MONITORING: TESTING THE VALIDITY OF LYON 2.0 RECOMMENDATIONS FOR WIRELESS pH MEASUREMENT. The results of this analysis validate the recommendation that prolonged reflux studies of at least 72-hr duration provide optimal AET measurements for GERD diagnosis. Prolonging studies can also resolve inconclusive results based on 24- and 48-hr studies. |
Validation and epidemiologic definition of the novel steatotic liver disease nomenclature in a national United States cohort with cirrhosis. Classification of SLD is highly sensitive to relative weighting of CMRFs and alcohol use. Clinically relevant definitions should consider data availability on alcohol and the limitations of lipid measurements in distinguishing SLD subtypes. |

Efficacy of anti-obesity medication (AOM) and endoscopic gastric remodeling (EGR): Analysis of combination therapy with optimal timing and agents. Combining AOM with EGR appears to result in greater weight loss compared with other strategies, with GLP-1RA as the preferred agent and optimal initiation of both therapies occurring within 6 months of each other. Prolonged medication use prior to EGR appears to be associated with suboptimal weight loss, suggesting the importance of early referral for adjunctive therapy. |

Enhancing HBV-specific T cell responses through a combination of epigenetic modulation and immune checkpoint inhibition. The combination of DAC/αPD-L1 shows promise in improving HBV-specific T cell responses in vitro, highlighting the potential of remodeling exhaustion-associated epigenetic signatures to enhance HBV-specific T cell restoration and suggesting a novel immunotherapeutic avenue for CHB. |
Interleukin 8-CXCR2 mediated neutrophil extracellular trap (NET) formation in biliary atresia associated with NET-Induced stellate cell activation. BA patients have persistent IL-8-CXCR2-mediated NETosis that correlates with biomarkers of injury and fibrosis and NETs induce stellate cell activation, suggesting a role for NETs in the immunopathogenesis of disease. Future investigations should focus on therapeutic agents that inhibit NETs in BA. |
International trends in biliary tract cancer-related mortality, 2000-2022: An observational study of the World Health Organization mortality database. Although internationally estimated BTC-associated ASRs showed a stable trend over the last two decades, a large increase in estimated iCCA-associated ASRs necessitates developing effective screening for high-risk individuals and disease management strategies. |
Lhx2 specifically expressed in hepatic stellate cells promotes liver regeneration and inhibits liver fibrosis. We demonstrated that Lhx2 had pro-regenerative and anti-fibrogenic functions, and elucidated its regulatory mechanism. The study provided a potential target with dual effects for treating liver diseases. |
Validation and expansion of Baveno VII criteria for cACLD and CSPH based on liver stiffness and platelet count: Correlation with risk of hepatic decompensation and death. The Baveno VII "Rule-of-Five" criteria provide a valid system for stratifying risks of death and hepatic decompensation and should be used routinely in patients with chronic liver disease. Among patients with CSPH (LS ≥25 kPa), the subgroup with LS 50-75 kPa ("critical" CSPH) has approximately double the risk of death and hepatic decompensation than LS 25-49.9 kPa. |
Value of HCC surveillance in a landscape of emerging surveillance options: Perspectives of a multi-stakeholder modified delphi panel. The panel acknowledged performance metrics of emerging methods may differ from other cancer screening programs given differences in populations, including higher risk of cancer development and competing risk of morality, and differences in diagnostic workflow in patients at risk of HCC. These data provide insights into the perceived value of HCC surveillance in an era of emerging blood- and imaging-based surveillance strategies. |

A read-through circular RNA RCRIN inhibits metabolic dysfunction-associated steatotic liver disease. Our findings provide an in vivo function of rt-circRNA RCRIN, show its inhibitory effects in MASLD pathogenesis, indicating RCRIN and RPL8 may be therapeutic targets and candidate nucleic acid drugs for treating MASLD. Impact and implications Our finds reveal a novel mechanism connecting a read-through circRNA RCRIN, ribosome heterogeneity and MASLD pathogenesis. In normal hepatocytes, RCRIN exerts its role by reducing liver lipid accumulation and ER stress through promotion of RPL8 degradation. In MASLD patients, lower RCRIN releases RPL8 to form RPL8-contained ribosomes to promote lipid accumulation and ER stress. RCRIN overexpression and RPL8 depletion dramatically suppresses MASLD development and progression. Our findings indicate that RCRIN and RPL8 might be potential therapeutic targets for treatment of MASLD patients. |
All-cause and cause-specific mortality in patients with chronic hepatitis B and concurrent steatotic liver disease. Among patients with CHB and SLD, metabolic burden dose-dependently increases the all-cause, liver-related, and cardiovascular mortality risks. Patients with SLD have a lower mortality risk than those without SLD. Identifying these metabolic dysfunctions is crucial for stratifying the level of risk in daily care. Impact and implications Concurrent steatotic liver disease (SLD) is prevalent among patients with chronic hepatitis B (CHB); however, the effects of the associated cardiometabolic risk factors on all-cause and cause-specific mortality remain unknown. This study demonstrated that cumulative metabolic burden dose-dependently increased the risks of all-cause, liver-related, and cardiovascular mortality in patients with CHB and SLD. Moreover, new-onset diabetes mellitus, hypertension, and weight gain during the follow-up period further exacerbated these risks. However, patients with SLD had a lower risk of mortality than those without SLD. Thus, routine screening and monitoring of metabolic dysfunctions constitute a key element of daily care for patients with CHB. |
Carvedilol vs. propranolol for the prevention of decompensation and mortality in patients with compensated and decompensated cirrhosis. Our data endorse the current recommendation favoring the use of carvedilol in the prevention of a first decompensation of cirrhosis and suggest extending the recommendation for its preferential use to patients with decompensated cirrhosis without recurrent or refractory ascites. Impact and implications This study addresses a gap in the comparative effectiveness of classical non-selective beta-blockers (e.g., propranolol and nadolol) versus carvedilol in managing cirrhosis in both compensated and decompensated stages. Our results support the preferential use of carvedilol in both settings due to its superior efficacy in reducing first and further decompensation. However, the retrospective nature of the study and inherent selection biases advise caution against broadly applying these findings to patients with decompensated cirrhosis who exhibit signs of circulatory dysfunction or recurrent/refractory ascites. |
Impact of metabolism-disrupting chemicals and folic acid supplementation on liver injury and steatosis in mother-child pairs. Pregnancy MDC exposures may increase risk for liver injury and steatosis, particularly in children. Adequate FA supplementation and maternal cobalt levels may attenuate these associations. Impact and implications The effects of environmental chemical exposures on steatotic liver diseases are not well understood. In a parallel investigation of mothers and children, we found that pregnancy exposures to metabolism-disrupting chemicals may increase the risk for liver injury and steatosis, especially in the child, and that these associations could be attenuated by higher folic acid and/or cobalt levels. These findings can inform policies to decrease environmental chemical pollution and contribute to the design of clinical interventions addressing the MASLD epidemic. |
Impaired whole blood thrombin generation is associated with procedure-related bleeding in acutely decompensated cirrhosis. In compensated cirrhosis, WB-TG and PPP-TG do not improve risk stratification. In decompensated cirrhosis, WB-TG may be a promising tool for estimating procedure-related bleeding risk. |

Incidence and clinical course of post-infectious irritable bowel syndrome in patients admitted to university hospitals: 1-year prospective follow-up study. The incidence of PI-IBS in Korea was relatively low, and most cases improved over time. No risk factors associated with the development of PI-IBS were found. However, persistent diarrhea after enteritis was associated with female sex, EPEC infection, and severe or long-lasting enteritis. IBS symptoms may persist after severe enteritis but usually improve with time. |
Randomized Multicenter Study to Evaluate the Efficacy and Safety of Fexuprazan According to the Timing of Dosing in Patients with Erosive Esophagitis. Non-inferiority analysis revealed that taking fexuprazan after meal was non-inferior to taking fexuprazan before meals in patients with EE. The frequency of adverse events was similar between the 2 study groups. The drug is safe and effective for healing EE regardless of the timing of dosing. |

A Call to Action: Unraveling the Nuance of Adapted Eating Behaviors in Individuals with GI Conditions. Further, we address the potential risk factors that gastroenterology clinicians should be aware of when assessing for disordered eating risk reduction. We hope to elucidate the "gray area" related to eating behaviors in patients with known physiological food intolerance such as FODMAP related immune activation in IBS and gluten related reactions in celiac disease in the gut and beyond, that prompt behaviors that are deemed maladaptive in healthy individuals but may be at times adaptive responses in GI conditions. |
